Quick Detail

Description

The 330105-02-12-10-02-CN 3300 XL 8 mm Reverse Mount Probe is a high-precision eddy current non-contact sensor engineered by Bently Nevada, designed to solve installation challenges in space-constrained industrial environments while delivering reliable vibration and position monitoring for critical rotating machinery. As a flagship member of the 3300 XL series, this 3300 XL 8 mm Reverse Mount Probe stands out with its innovative reverse mount design, which enables deployment in narrow cavities, tight bearing assemblies, and special-angle mounting positions where traditional probes cannot fit—making it the preferred choice for industries requiring high-precision condition monitoring in complex layouts. Manufactured in the USA and supplied in original factory-sealed packaging, this 3300 XL 8 mm Reverse Mount Probe complies with the stringent requirements of API 670 standards, ensuring world-class performance in mechanical structure, measurement accuracy, and temperature stability.

Operating on proven eddy current technology, the 330105-02-12-10-02-CN 3300 XL 8 mm Reverse Mount Probe produces an output voltage strictly proportional to the gap between its probe tip and the measured conductive surface, enabling simultaneous capture of static position parameters (e.g., rotor axial displacement) and dynamic vibration signals (e.g., fluid-film bearing vibration amplitude). With a 2 mm (80 mils) linear measurement range, 50 Ω output resistance, and supply sensitivity of less than 2 mV/V, this 3300 XL 8 mm Reverse Mount Probe delivers consistent, low-noise data even in harsh industrial environments with extreme temperature fluctuations (-52°C to +177°C) and intense mechanical vibrations. Its compact mechanical design—featuring a 0 mm minimum unthreaded length, 60 mm (2.4 inches) overall case length, 1.3x1.1x56cm dimensions, and 0.08kg weight—further enhances its adaptability to tight installation spaces, while the miniature ClickLoc coaxial connector and 1.0-meter (3.3 feet) cable ensure secure, interference-free signal transmission and easy maintenance.

Applications

The 330105-02-12-10-02-CN 3300 XL 8 mm Reverse Mount Probe is widely used in power generation facilities for monitoring critical rotating equipment such as gas turbines, steam turbines, and reciprocating engines. Its compact reverse mount design enables installation in narrow turbine bearing housings and rotor axial clearance measurement points, while its -52°C to +177°C operating temperature range ensures stable performance in both freezing outdoor substations and high-heat turbine enclosures. The probe’s 2 mm linear range accurately captures rotor vibration and axial displacement data, supporting predictive maintenance programs to prevent unplanned power outages and extend equipment service life.

In petrochemical refineries and chemical processing plants, this 3300 XL 8 mm Reverse Mount Probe excels at monitoring centrifugal pumps, compressors, and pipeline turbomachinery—equipment operating in corrosive, high-vibration environments with limited installation space. Its CSA, ATEX, and IECEx certifications allow direct deployment in hazardous zones (Zone 1/2), while the AISI 303/304 stainless steel case and PPS probe tip provide excellent corrosion and wear resistance against oil mist, chemicals, and industrial contaminants. The probe’s ability to collect Keyphasor reference signals also supports precise speed measurement for rotating equipment, ensuring compliance with strict industry safety standards.

Specifications

Competitive Advantage

1.Innovative Reverse Mount Design for Space-Constrained Installations

The 330105-02-12-10-02-CN 3300 XL 8 mm Reverse Mount Probe features a proprietary reverse mount structure that solves the deployment challenges of traditional probes in narrow cavities, tight bearing assemblies, and special-angle mounting positions. With a 0 mm minimum unthreaded length, 60 mm overall case length, and lightweight 0.08kg design, it fits into spaces where standard 8 mm probes cannot be installed—eliminating the need for costly equipment modifications and expanding application scenarios in complex industrial layouts.

2.API 670 Compliance & Hazardous Area Certification

This 3300 XL 8 mm Reverse Mount Probe fully complies with API 670 standards, meeting world-class requirements for measurement accuracy, temperature stability, and mechanical reliability—critical for critical equipment in power and petrochemical industries. It also holds CSA, ATEX, and IECEx certifications, enabling direct installation in explosive hazardous zones without additional safety accessories, streamlining compliance processes and reducing project lead times.

3.Full Interchangeability & Backward Compatibility

Unlike competing sensors that require matched component sets and lab calibration, the 3300 XL 8 mm Reverse Mount Probe achieves full interchangeability with same-series extension cables and Proximitor sensors, significantly reducing maintenance downtime and spare parts management costs. Its excellent backward compatibility with non-XL 3300 series 5 mm and 8 mm transducers also protects users’ initial investments, allowing seamless upgrades of legacy systems without full hardware overhauls.
